在临界装置上进行堆芯温度系数测量

Measurement of Temperature Coefficient of Core in Critical Facility

本文介绍了在临界装置上进行堆芯温度系数测量的方法、测量仪器、实验结果及校核计算结果。实验结果表明,温度系数均为负值,满足反应堆设计的安全要求;实验结果与校核计算结果相符,验证了堆芯核设计程序的可靠性。

The paper introduces the measurement methods,instruments,experimental results and calculation results of temperature coefficient of the core in the critieal facility.The experimental results show that measurement values of temperature coefficient are all negative,which satisfy the safety requirement for the design of reactors.The experimental results are eorrespondent to calculation results of temperature coefficient of the core,which verifies the reliability of core design codes .
